Normally, it is very tough to imagine the contrast in sensor sizing only by going through technical specs. The graphic underneath should give you a clearer sense of the sensor sizing in the E-M1 III and E-M5.

As you have seen, each of the cameras come with the identical sensor size but different resolution. You should expect to see the Olympus E-M1 III to provide more detail with its extra 4 Megapixels. Greater resolution will allow you to crop photos a good deal more aggressively. The more recent E-M1 III should have a benefit in sensor technology.
